Precautions on Moving Coils with Polarity Sensors
Note
When you use a Moving Coil with a Polarity Sensor, the Magnetic Way must cover the bottom of
the polarity sensor. Refer to the example that shows the correct installation.
When determining the length of the Moving Coil’s stroke or the length of the Magnetic Way, consider
the total length (L) of the Moving Coil and the polarity sensor. Refer to the following table.
